I don't know security that well but if the puregym app refreshes the token then the old tokens would expire immediately right?

  Nope. As I read it, any token less than a week old would work. So for any user, they have 7 * 24 * 60 tokens live at any time.

    He said the code from Monday didn't work on Tuesday

      Yeah, screenshot on Monday, messed with the app that evening, tried using it Tuesday morning -- dead. I've seen people on PureGym's Twitter successfully refreshing screenshots weekly though, and the API response suggests the same. That being said, I couldn't find a validation endpoint to check if mine got invalidated by something specific (maybe signing out?) or if there's some other magic happening.

        I wonder if opening the app invalidated it, and those people who had it working just screenshot once. My gym has a similar system but I realised it's time based and the app functions without Internet. I installed the app onto an old android with no sim, logged in at home over WiFi and it successfully regenerated QRs without data
